How to work it out

  1. Turn the percentage into a decimal: 99 ÷ 100 = 0.99
  2. Multiply: 0.99 × 72 = 71.28
  3. Check: Work backwards: 71.28 ÷ 72 × 100 = 99%.

Another method. As a proportion of part to whole: 99/100 = part/72, so part = 99 × 72 ÷ 100 = 71.28. Both methods always give the same answer.

In a spreadsheet: =99%*72. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.

What the result means

71.28 is the 99% share of 72. The remaining 1% is 0.72, and the two parts add back up to 72.

Discounts: 99% off an item priced $72 saves $71.28, so you pay $0.72.

Adding and taking away 99%

Increasing 72 by 99% gives 143.28 and decreasing it by 99% gives 0.72. These do not cancel out: raising 72 by 99% and then lowering the result by 99% ends at 1.4328, because the second 99% is taken of a bigger number.
